By Heide Brandes OKLAHOMA CITY (Reuters) - Hundreds of people gathered in stormy weather on Thursday to mourn a 9-year-old girl who loved to sing, dance and paint, as funerals began for 24 victims of a massive tornado that obliterated whole sections of Moore, Oklahoma. Antonia Lee "Tonie" Candelaria was one of seven students killed at Plaza Towers Elementary when a tornado packing winds of 200 miles per hour slammed into the building on Monday afternoon just before school was to have let out.
